High Roller makes its first and only appearance in the level "Team Player". It can be found located on a small ridge to the left of the level's starting point remaining stationary, next to a destroyed fellow M1A2 Abrams. From there High Roller is seen providing covering fire to the Rangers as they engage the OpFor forces located across the river, in an attempt to protect bridgelayer Bigfoot from being destroyed so the Ranger's convoy can proceed into the Afghan town.

In this process High Roller will fire its main gun several times, one round destroying an enemy BMP-2 and the others appearing to be misses landing in the river. After the Rangers are able to repulse the OpFor counter attack, the player can still see High Roller from the bridge, remaining stationary. After crossing the bridge High Roller is out of the player's sight and never seen again in the game, making it likely that the vehicle and it's crew survived the events of Modern Warfare 2.
